STEERING MECHANISM FOR TRACTORS.

Specification of Letters Patent. Patented F 1 28 1922 Application filed April 7, 1921. Serial No. 459,283.

T 0 all whom it may concern Be it known that we, ERIC N. SMITH and HERBERT H. DILLINGER, citizens of the United States, residing at Hoytville, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Steering Mechanisms for Tractors; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved steering mechanism for use in connection with a tractor so that the tractor may be steered by the operator of a vehicle or wheeled implement connected with the tractor thus making it unnecessary for theperson steering the tractor to ride uponithe tractor. This device is to be used in connection with a tractor having a control mechanism shown in connection with the companion application filed Feb. 21, 1921, Serial No. 446,815. It has been found that when in use,- a tractor jolts and isvery hard and disagreeable to rid and therefore the structure shown in this application and thecompanion application referred to above'have by the tractor.

been provided to permit the tractor to be controlled and steered by a person Occupying the vehicle or'wheeled implement drawn This invention is illustratedin the accompanying drawings, wherein:

Figure 1 is a perspective view showing a tractor provided mechanism.

Figure 2 is a sectional view through the line carrying drum, the section being taken along the line 22 ofFig; 1.-

This improved steering mechanism is used in connection with a tractor indicated in I general by the numeral 1 and provided with control mechanism as shown in the companion application, Serial No; 446,815. This controlling 'mechanism""whi'ch is not described in detail provides a supporting structure and includesa housing 2' carried with 1 the improved steering 6 which ordinarily carry the drivers seat. A bracket 7 is placed: upon the housing 2 and is engaged by the inturned fingers 8 at the upper ends of thearms of the yoke 5. This bracket is further provided with a longitudinally extending slot 9=through which extends the securing bolt 10 carried by the upper wall of the housing-2 so that when the securing bolt 10 is released, the bracket can be moved longitudinally of the housing, and then secured in theadjusted position by again tightening the bolt. This bracket 7 has its arms 11 carried upwardly and then bent inwardly to provide -supporting feet 12 upon which will rest the tubular line guides 13. These tubular line, guides are engaged by the clamps 14' which are secured to the seat 12 by bolts 15 and itwill thus be seen that "by loosening the bolts 15, the tubular guides can bereleased and. thus entirely re-,

moved or adjusted longitudinally; of the bracket andth en again secured by tightening the bolts. The forwardend portions of these tubular guides are bent to extend .in; diverging relation and in the preferred form, these tubularguides or pipes will be formed of some; material which will permit them to be bent to extend in diverging rela-, tion' at an angle which will guide the end portions 16 of the steering lines in the most effective manner. Y

.The tractor is provided with a steering wheel 17 and a drum will be secured to this stecringrwheel as shown. This drum is provided with an inner rim or ring 18 which is curved in cross section as shown in Fig. 2 so that the steering line may have its central portion secured to the rim and its end portions passed about the rim in opposite directions and in crossed relation and then passed through the tubular lines or guiding pipes 13. It should be noted that when thedevice is in use, these pipes will be positioned with their forward end portions close to the run and curved' so that the end portions of the lines will pass freely through the guiding pipes onto or off the rim portion of the drum, Gross strips 19 which resemble spokes extend across the space within the rim 18 and have their end portions bent downwardly shown at 20 and secured to the inner face of the rim by rivets or other suitable fasteners 21. The end portions of the strips 19 are then carried outwardly beyond the rim 18 as shown at 22 and have their end portions bent upwardly to provide fingers 23 which will be secured upon the-outer face of a ring 24 positioned in spaced relation about the line carrying rim 18. The curved forward end portions of the pipes 13 extend over this ring 24 and the ring will off of the same, this portion will be supported and will move back onto the rim when the lines are again tightened. This drum will be put in place as shown and will be secured to the steering wheel in any suitable manner, U-bolts 25' being employed in the present instant and engaging-the spokes of the wheel 17. The present disclosure illustrates one'forin of line carrying. drum and it is to be understood that other forms may be substituted for thespecific structure shown and further that if desired", the line carrying drum could'be directly connected with the steering post instead of being connected with a steering wheel carried by the post.

We claim: 11. A steering mechanism comprising a supporting structure to be mounted to the rear of: a steering wheel, tubular guidescarried by said supporting structure and having their forward end portions extending in diverging relation for extending circumferentially of a steering wheel, the tubular guides being adapted to receive the end portions of a steering line having its intermediateportion passed about a steering wheel in front of said bracket.

2; A steering mechanism. comprising a porting structure, a bracket carried by and adjustable longitudinally of. the supporting structure and having upstanding arms bent to provide heads, tubular guides secured to the heads of the bracket and extending longitudinally of said bracket and having their forward end portions extending in diverging relation, and a steering line for rim, a supporting structure mounted to'the rear of the steering wheel, and tubular steering line guides carried by said supporting structure-and having their forward end portions extending across said outer rim and terminating adjacent said'inner rim.

6. The combination with'a vehicle inoluding a steering wheel, of wheel control mechanism including an auxiliary wheel carried by said steering wheel and constituting a steering line drum, a supporting structure carried by the tractor to the rear ofthe steering WheeLiand'tubuIar steering line guides carried'by the supporting structure and having their forward end-portions extending} in diverging relation withtheir forward ends 1 adjacent thedrum. 1 1

- 7. Thecombination Withavehicle including a steering wheehof wheel control mechanism including a steering line drum car ried by said steering wheel, a-supporting' structure adjacent said steering wheel, and tubular steering: line guides carried by the supporting structure and extendingradially of the druin' and terminating adjacent the drum to receive end portions of. a steering line passed about the drum;

8. The structure of claim 7- having the supporting structure including a-bracket for carrying the tubular line guides adjustably. mounted for movement towards and away 'i'rom'the drum.

9. The structure of claim 7 havingthe; supporting structure including a bracket for carrying the tubular line guides adjustably mounted for movement towards and away from the drum, and clamps releasably holding the guides in engagement with" the bracket; f

10. A steering mechanisnr of the character described including a'drum. comprising a line carrying rim,.an outer ring about said rim, and strips extending in crossed relation and. having theirend pmions bent toe tend" down beneath the rim and outwardly to engage said ring, the. bent end, portions being securedrto the:- rimmi'd ringi and the intermediate portions being adapted for connection With a steering Wheel.

11. A steering mechanism of the character described including a line carrying ring, an

outer ring, and strips having their intermediate portions extending across space enclosed by said line carrying ring and their end portions connected with the rings and ERIC N. SMITH, HERBERT H. DILLINGER.
